Application filed March 26, 1915. Serial No. 17,279.

v To all whom it may concern:

Be it known that I, ERNEST E GENE TOWARD, a citizen of theUnited States,.and a resident of Portland, county of Mult nomah, and State of Oregon, have invented a new and useful Improvement in Lawn- Sprinklers, of which the following is a specification.

My invention relates to lawn sprinkllng devices'and particularly to that class thereof which are automatic in action, and are adapted to sprinklean extended area without attention.

()ne of the main objects of my invention 1s to provide a sprinkling apparatus of this character which is of simple construction, and operated to automatically sprinkle a sectional area of the lawn, the device being operated by the pressure of the stream of water emitted from the nozzle.

Another of the main objects of my invention is to make the device adjustable so as to vary the sectoral area over which the water issp'rinkled. I

The features of my invention and its details are hereinafter fully set forth and illustrated in the accompanying drawings, in which a Figure 1 is a side elevation of my device, showing itin actual use; Fig. 2 isa top view of the parts shown in Fig. 1, the circular line showing the sectoral area through which my apparatus acts; Fig. 8 is a largerscaleside elevation of my device, viewed from the side opposite to that shown in Fig. 1; Fig. 4L is a bottom plan view of the parts shown in Fig.3; this view details the mechanical movement which operates my device. Fig. 5 shows the adjustable clamp by means of which the hose is held in position, and Fig. 6 is a cross-section taken on the plane of the line 66 of Fig. 3.

a represents a rod, which may be made of a piece of pipe. The bottom of the rod is provided with a pointed end 5, adapted to be thrust into the ground, so as to hold said rod at any angle desired. In the upper end of said rod is provided a journal end a, (see F ig. 3) and a spurgear (Z is nonrotatably fixed on said journal end. The double ended arm 6 is provided with a hub f, r0-.

tatably mounted on the journal end 0. The lower face of the arm 6 rests on the upper end of the hub g, of the gear (Z. The end it, of the arm 0, is curved downwardly and is provided with a cup-shape sleeve 2', in which clamp j may be rotated relative to the axis of the sleeve 2', so that the nose held by said clamp may be given any pitch desired. By

tightening the nut-m,the pivoted jaws of the clamp j, will be drawn within the cupshape sleeve i, and will thus be forced t0- gether as indicated in Fig. 5.

The end a of the arm 6 supports the motion-transmitting devices. These consist of a worm-gear Q pivotally mounted on a downwardly projecting shouldered stud it, provided on the end it of the arm 6. The extremity of the end at of the arm 6 ismade with a laterally projecting journal bearing p, in which a journal pin or shaft 1" is journaled. A worm s, meshing with and adapted to drive the 'u-orm-gear g, is fixed on one end of said pin 1', and on the other end of the latter is fixed a'wa't'er-wheel t, the blades of which are indicated by a. It is evident therefore, that the rotation of the turbine wheel will drive the worm gear 9.

The lower face of the worm-gear g is provided with a plurality of tap-holes o, (see Fig. located inradial alinement with the center of the gear. A crank-arm w is pivotally connected to said worm-gear by a screw to, which is adapted to be threaded into one of the holes 0. The crank-arm w is provided with rack-teeth a meshing with the gear (Z, and is further made with a supporting member 2, parallel to the rack-teeth. The arm a encompasses the hub of the gear (Z, and rides on the upper face ofthe gear (Z and in so doing supports thecrank-arm w.

2 represents a In practice the nozzle end of the hose 2 is brought up as close to the rod a as possible,

garden hose having a noz- (see Fig.1) and is supported by the clamp j, l

ward movement aboutits vertical pivot,

thereby sprinkling the water uniformly over a sectoral area as indicated by the circular by confining the sprinkling to a smaller-sectoral area.

Since my device does not make a complete revolution about its vertical aXis, it may be used in many places where a completely revolving sprinkling apparatuswould be impractical. Furthermore, the apparatus'may be moved about from one place to another without being required to turn ofilthe water supply in order to reach the apparatus as is necessary in prior devices.

In order to adapt my device to use under different conditions, I prefer to make the rod a of two parts, the upper part having a member 5 telescoping in the lower part, as shown in Fig. 1 and the upper part further having a joint 8, so that the rod can be adj usted to any convenient length and that the upper part may be adjusted at any convenient angle. Such adjustment. facilitates the confining of the sprinkling to; a pre scribed area of the lawn. Furthermore, in order to avoid imposing too much weight on the arm 6, I prefer to provide on the rod (4, a supplemental hose clamp 41:, rotatably supported on a collar or flange 3. These details are all shown in Fig. 1.

I claim:

1 In a device of the character described, the combination of a supporting member, an arm pivoted on such supporting member, a hose-holding means on one end; of the arm, a Water-wheel rotatably journaled on the 1 other end of the. arm, and adjustable means operated by the water-wheel for imparting to the arm a variable oscillatory movement.

2. In a device of the character described, the combination of a longitudinally variable supporting member, an arm centrally ivoted on such supporting member, an ad ustable hose-clamp. on one end of the arm, a waterwheel. rotatably journaled on the other end of the arm, and adjustable means operated by the water-wheel for imparting to the arm a variable oscillatory movement,
